STERILIZING' AND" WATER-HEATING DEVICE,

Application filed February To all whom-it may concern:

Be it known that LEbwnnn IiRONMAN, a citizenof the United States, and a resident Of'the borough of Manhattan, city, county,

and State of New York, have inventedcer tainnew and useful Improvements in Sterilizing and ater-Heating Devices, of'which the following is a specification sufficient ato enable those skilled'in the art to whichthe 1 invention appertains to utilize the same.

My improvements relate to sterilizing and water heating. apparatus generally, but more particularly to the type of'such apparatus designed for use in barber shops, hospitals, and otherplaces in which a continuous supply of hot water for shaving, washing, and analogous purposes is desirable, in conjunction with means for effecting the sterilizing of large quantities of towels, napkins and the like for sanitaryreasons, substantially as set forthin Letters Patent #1,508,187 issuedrto me September 9th,192'l-,my present invention'relating more particularly to the sterilizing hood and its connection with the body or tank section, of the apparatus, and consisting in the: specific combination, construction and arrangement of parts and appurtenances described and claimed, whereby certain advantageous results are attained, all [as hereinafter set forth.

In the. accompanying drawings I illustrate a practical embodiment of the essential fea tures of my invention in conj unction with i a barbers water heating and sterilizing ap paratus of the character designated, al though I do not limit myself to the identi cal construction of parts shown by wayof exeinplification, since changes may be made in minor details, andequivalent mechani cal enpedients resorted to witlrlike results, and without departing from the spirit and intent ofmyinvention in this respect.

\Vith this understandings" Fig. 1, is a'front elevation of "suchapparatus, with the sterilizing dome in closed position;

F ig. 2, is a front elevation of theupper part of the apparatus, with the dome in'open position;

in closed position, and; indicating the presence of towels or like articles forsterilizatron;

Fig. "12,1s a view of the undersideofthe hood as removed from the-neck ofthecasingor superstructure of thapparatus The mternalarrangement, construction and operationof the apparatus A, below the neck portion A, thereof is essentially the sameas (lQSCllbGCl an my aforesaid Letters considered further herein, except for thee-O fact that the steam for sterilization in the dome D 1 is derivedtherefrom,

The interior of a said hood or dome 1),, constitutesthe sterilizing chamber D, the dome D being i of essentially g globular configura tion, and being rotatably mounted on the neckA, of the apparatus, preferably on ball bearings b, I), positioned in an annular groove or raceway n, forming an integral part of the upperextremity of said neck A, as shown moreparticularly i11 Fig. 5, of the drawings, by reference to i which it will also be understoodithat said neck=A, is furthermore formed witha rigid-integral cylindrical sleeve (4, having a concentric-inner D5 cylindrical sub-sleeve a the-lower portions of saidsleeve a,and its sub-sleeve a being integrally united by a connective flange a the said three--partsa, a forming a pocket a", forthe accommodationof a cylindrical sleeve (F, on the base of-thedome D, as hereinafter set forth.- The sub sle'eve a has-rigidly attached to its inner surface at one side thereof the socket a, for tlie-1-eception andsupport'ofthe shank-s, of-thestand ard s, onthe upper extremity of whichthe stationary shutter S, is rigidly mounted.

The lower portionof the domeD, is truncated and formed with a basic annular flange 62, of sufiicient depth to form a housing for the annular rail d, which, when the dome D, is in position on the neck, i rests upon the aforesaid encircling series of ball rollers, Z), 5, thus constituting an anti-friction bearing upon which said hood or dome D, is rotatably supported, it being understood that the rail d, is rigidly attached to the inner side of said basic flange d, and aid rail d, being formed with a pendent cylindrical flange (8, which fits within the pocket (4*, between the sleeves a and a, of the neck A, hereinbefore referred to.

The sterilizing chamber D, is provided with a removable drainage lloor f, formed with a pendent cylindrical extension f, which, when the floor f, is in normal position within the sterilizing chamber D, extends down into the sub-sleeve (1.", both the floor f, and its said cent 'al cylindrical extension j", being formed with perforations which provide for the admission of steam from the neck A, to the sterilizing chamber D,-the steam ascending through the subsleeve (1 and the cylindrical ilange d, on the annular rail cl, functioning as a trap or shield to exclude the steam from said anti-friction ball hearing.

The draining floor 7', is formed with a recess 7, for the accommodation of the standard 3, of the stationary shutter S, both the latter and the drain floor ,2, being removable upon occasion, as for purposes of cleansing, through the access aperture D formed in the upper portion of the dome D, primarily for the purpose of affording access to the interior of the sterilizing chamber D, f or the insertion or removal of clothes to be impregnated with steam in said sterilizing chamber in a manner heretofore well known in the art. Said access aperture D being closed normally by the stationary shutter S, as indicated more particularly in Fig. 12, ol' the drawings, which also illustrates the function of treatment of clothes supported on the drain floor 7'.

The stationary shutter S, is positioned at the rear of the sterilizing chamber 1), so that when the access aperture D, in the dome is closed thereby, as in Fig. l, of the drawings, the apparatus, viewed from the front particularly, is oi symmetrical ap pearance, the access aperture D", being at the rear end and out of sight. This is dcsirable from an esthetic point of View, whereas when the dome is turned with the access aperture 13*, to the front said aperture may be freely and conveniently used either for the insertion or removal of towels or other analogous clothes subject to treatment. By reference, the dome is provided with an annular handle cl, rigidly attached to the exterior of the basic flange (1, and oi elliptical form in cross section, as shown more particularly in Figs. and 11, oi? the drawings, although this is not an essential :ifeature of my invention, since any suitable mechanical (-uqiedients may be resorted to, to facilitate the rotation in the hood 1), on the neck A.

lrhat I claim as .niy invention and desire to secure by Letters Patent, is

1. in water heating and sterilizing aparatus ot the character designated, the combiinitioi'i with the neck oi? the steam gen orator, etc, oi a sterilizing hood ri'itatably mounted on said neck and formed with an access aperture on one side thereof, a stationary shutter positioned within said hood, means for manually rotating said hood, and a perforated drain floor in said hood formed with a recess to accoi'nlnmlate the standard supporting said stationary shutter, substantially in the .manner and for the purpose set forth.

2. In water heating and sterilizing apparatus ot the character designated, the combination with the neck ol the steam generator, etc., of a sterilizing hood rotatably mounted on said neck and formed with an access aperture on one side thereof, a stationary shutter positioned within said hood, and a perforated drain floor in said hood formed with a recess to accommodate the standard supporting said statioiutry shutter, said stationary shutter and said drain lloor being insertable and removable through said access aperture in the hood, substantially in the manner and for the pur pose set forth.

3. In water heating and sterilizing apparatus ot the character designated, the combination with the neck of the steam generator, etc, of a sterilizing hood formed with an access aperture on one side thereof, and rotatably mounted on an annular series of ant-i-l riction rollers positioned in a groove on said neck, said hood being formed with an annular rail resting on said rollers, and with means 'l'or manually rotating said hood and a statioinu'y shutter positioned within said hood, substantially in the manner and for the purpose set l'orth.
